•
The distribution coefficient (Log D) defines the distribution of a compound
between an aqueous and a lipid phase
•
A greater affinity for the lipid phase may favour tissue penetration
•
Macitentan may have a greater affinity for the lipid phase compared with
other ERAs*

Considerazioni conclusive
• L’utilizzo di trattamenti specifici per l’ipertensione arteriosa
polmonare ha condotto ad un miglioramento della
sopravvivenza (+ 10-15% annuo)
• Attualmente l’approccio consigliato è una terapia di
combinazione sequenziale in caso di mancato
raggiungimento dei target terapeutici
• Sta emergendo l’efficacia di terapia di combinazione
upfront
• E’ fondamentale adottare una strategia terapeutica
aggressiva che contempli l’uso dei prostanoidi parenterali
• Necessaria collaborazioni tra diversi centri per uniformare
gli approcci diagnostici-terapeutici
